“…Working on basins like Omerli Basin, which are highly affected by urbanization, requires more data, further analysis, application of infrastructure models, and other tools to aid decision makers, to address water potential studies properly, and to better understand the complex interactions between catchment and in-stream processes in urban systems as stated by Welty et al (2007) andO'Driscoll et al (2010). and Ahn et al (2016) investigated the effects of using different LULC datasets on hydrological modeling; however, these studies were restricted to limited comparison of LULC datasets for the same period. Branger et al (2013) also successfully evaluated the influence of land-use data on the water balance components of semi-urban basin.…”

Both Sadek et al (2014) and Ahn et al (2016) studied impact of LULC datasets on river flows at basin level. On the contrary, model outputs of this study evaluated different land-uses at sub-basin level, and also considered model parameterization uncertainty using SUFI-2 algorithm.…”

“…They revealed that using different datasets can induce important changes in the model response; however, these differences may not be necessarily spectacular in terms of total discharges, although more visible for the less urbanized subcatchments. In a study conducted by Ahn et al (2016), SWAT model was used to simulate the streamflow and water quality predictions were done in an agricultural watershed located in northwestern part of South Korea by utilizing KOMPSAT-2 and LANDSAT datasets belonging to 2004 and 2007. Their simulations showed high uncertainty in streamflow and water quality estimations due to the scale effect from the spatial resolution of different LULC datasets.…”

Land use/cover (LULC) dataset can be addressed as one of the significant factors governing watershed hydrology. Thus, there is a necessity for using appropriate LULC data especially while working on the hydrology of sensitive watersheds from which drinking water is provided. The aim of this study is to analyze the effect of using two different LULC datasets on the hydrological components of a basin in Turkey. Omerli Basin that covers one of the important drinking water reservoirs of Istanbul with a drainage area of 621 km2 is selected as the study area. The Soil and Water Assessment Tool (SWAT), a physically-based hydrological and public domain model, is used as the hydrological model to evaluate the water budget of the basin. SWAT model is calibrated with an automatic calibration and uncertainty analysis program (SWAT-CUP) by using SUFI-2 algorithm. Model setup is conducted for two different LULC datasets which are CORINE obtained for year 2006, and LULC data produced from 2006 dated Landsat satellite image. This pioneer study evaluates and compares the impact of CORINE and Landsat LULC datasets used in hydrological modeling by using SWAT model at sub-basin level. It revealed that different LULC datasets yielded quite similar results in terms of surface water runoff and actual evapotranspiration in the Omerli Basin; however, different spatial distribution was observed especially in urbanized sub-basins. Despite the coarser land-use classification in Landsat data, it enabled the detection of different LULC classification with higher spatial resolution, and thus, different model outputs were achieved especially in the urbanized sub-basins.

The Soil and Water Assessment Tool (SWAT) is an ecohydrological watershed-scale model which was initially developed in the early 1990s to simulate the impacts of land use, management systems, and climate on hydrology and/or water quality. First adopted in the U.S., the use of the model then spread to Europe and then later to Asia and other regions. The range of applications that SWAT has been applied to have also expanded dramatically, which influenced ongoing model development which has been virtually continuous over the past two decades. A key component of many SWAT applications in Asia is accounting for rice paddy production that is common in some subregions within the continent. However, most of these studies do not provide explicit details of how rice production was simulated in SWAT. Other research has revealed that significant problems occur when trying to represent rice paddy systems in standard versions of SWAT, due to limitations in algorithms based on the runoff curve number approach or the pothole option. In response, key modifications have been made to SWAT in recent studies that have resulted in a more accurate representation of rice paddy systems. These developments point to the need for the incorporation of an enhanced rice paddy module within SWAT to better capture rice paddy hydrological and pollutant dynamics, which would support improved use of the model in Asia and other rice production regions. Subtopics related to simulating rice production in SWAT are discussed as follows: 1) an overview of global rice production; 2) history of SWAT development; 3) typical approaches for simulating rice production; 4) problems associated with the typical approaches; 5) recent code modifications to address deficiencies in replicating rice paddy systems; 6) recommendations for developing a standard rice paddy module for future SWAT codes.
